His third solo album in the Katalyst trilogy was entitled Deep Impressions and was released in 2011 on INVADA / BBE. Of the title and creative method behind his third release, Katalyst says “Writing music for me is a continual process so when it came time to put the third Katalyst album together I looked at the songs I had written and recorded for the new release. As a body of work it was clear that many styles of music have made a deep impression on me as a producer. Hence the name of my album.” This album was also met with critical acclaim. It was nominated for an ARIA Award in 2012 for Best Urban Album.
2012 has seen Katalyst making big moves internationally, being signed to legendary Californian label Stones Throw Records with his latest release Quakers.
